Recipe yields 8 servings
Preheat oven to 350°F. Lightly grease a 13” x 9” casserole dish with nonstick cooking spray; set aside.
Prepare an ice bath in a large bowl. In a large pot of lightly salted boiling water, cook green beans until bright green and tender, about 5 minutes. Transfer the green beans to the prepared ice bath using tongs or a slotted spoon. Drain in a large colander and transfer to the prepared casserole dish.
In a medium saucepan, heat the oil and butter over medium heat until butter is melted. Add the shallots and cook until it begins to brown and turns translucent, about 5 minutes. Add mushrooms and cook, stirring frequently, until mushrooms are browned, about 5 to 7 minutes. Add the garlic and flour; cook for 1 minute.
Add the stock and milk while whisking constantly until fully incorporated. Add the cornstarch and stir until completely dissolved. Bring the mixture to a simmer and cook until the sauce begins to thicken, about 3 to 5 minutes.
Remove from heat. Add the black pepper, thyme, sage, paprika and salt; stir until well combined. Pour roux over the green beans and gently stir to combine. Top with shredded cheddar cheese.
In a small mixing bowl, combine the corn flakes, butter and black pepper. Sprinkle evenly over the casserole.
Bake uncovered for 25 to 30 minutes, until casserole is hot and bubbling in the center. Remove from oven and allow to rest for 5 minutes. Garnish with sliced green onion and enjoy immediately.
